Setting realistic fitness goals involves assessing personal capabilities, interests, and available resources. Start by defining specific, measurable, achievable, relevant, and time-bound (SMART) goals. For example, instead of a vague goal like "getting fit," one might aim for “running 5 kilometers in under 30 minutes within two months.” It's important to break larger goals into smaller milestones to maintain motivation. Regularly reassessing progress and being flexible with goals ensures they remain appropriate and achievable, making the journey toward fitness more rewarding and sustainable.
